McAllen is waking to clear skies and temperatures around 72 degrees Wednesday morning. The day will stay sunny and rain-free, with temperatures climbing to about 85 degrees before a sharp warmup and storm chances arrive later in the week.

Sunny Wednesday Leads Into A Hot Thursday

Northeast winds around 6 to 9 mph will accompany Wednesday’s sunshine, followed by a mostly clear night with a low near 70. Thursday turns mostly sunny and hotter, with a high near 92.

Storm Chances Arrive Thursday Night

Rain showers and thunderstorms become increasingly likely Thursday evening and overnight, with precipitation chances near 80%. The National Weather Service says the highest odds may be closer to the Lower Texas Coast, but the threat will extend across the Rio Grande Valley.

Cooler, Breezier Weather Takes Over The Weekend

Friday could bring showers before noon, followed by partly sunny skies and a high near 83, with wind gusts reaching 22 mph. Saturday stays warmer near 80, with showers possible later that day, while rain chances increase Saturday night and Sunday; regional highs are forecast in the mid-70s to mid-80s Friday through next Monday.

Conditions settle Monday with mostly sunny skies and a high near 76, followed by a partly sunny Tuesday near 80. No watches or warnings are posted for the area in this forecast, but outdoor plans from Thursday night through Sunday may need a rain-and-wind backup plan.
